WIRE LATHING.

SPECIFICATION forming part of Letters Patent No. 228,030, dated May 25,1880. Application filed March 1, 1880. (No model) To all whom it mayconcern Be it known that I, WILLIAM BRENNAN, of the city, county, andState of New York, have invented a new and useful Improvement inSupportingWire Lathing, of which the following is a specification.

Figure l is a sectional elevation of the improvement. Fig. 2 is anunder-side View, part being broken away.

Similar letters of reference indicate corresponding parts.

The objectof this invention is to support wire lathin g in ceilings insuch a manner as to leave no air-spaces between the beams and themortar, which spaces, in case of fire, serve as draft-fines, and thuscause the fire to spread rapidly, and increase the difficulty ofcontrolling the fire.

A represents the beams of a ceiling, and B represents the wire-nettingwhich serves as a lathing, and to which the mortarO is applied. The wirelathing B hasheretofore been applied to furring attached to the beams A.This construction is objectionable, from the fact that the mortar couldnot rise high enough above the wire lathing to fill the spaces betweenthe said lathing and the beams, which spaces, in case of fire, act aslines to draw the fire into and cause it to spread through the ceilings,rendering it very difficult for the firemen to get at the fire andcontrol it. To remove this difficulty I attach iron rods D to the loweredges of the beams A transversely by means of staples Eor other suitablemeans, and then attach the wire lathin g B to the rods D by wires F orother suitable means. With this construction the mortar O entirely fillsthe spaces between the lower edges of the beams A and the wire lathing Band surrounds the lower part of the beams A, so that there will be nospace for the passage of air between the beams and the mortar, andconsequently fire cannot spread through the ceiling.

Having thus described myinventioml claim as new and desire to secure byLetters Patent Y A wire lathing secured to beams A by rods D, staples E,and wires F, as shown and described, for the purpose specified.
